RADIATOR.

Application tiled-November 23, 1914. Serial No. 878,432.

To all whom it 1n a i conccl'n lie it known that 1. Run R. F. S'rin-ncnear. a citizen of the United States of America. residing at Detroit. in the county of \Vayne and State of Michigan, have invented certain new and useful Iinprovemc- .s in Radiators, of which thefollowing is a specifiCation, reference being bad therein to the accompanying drawings.

This invention relates to radiators for water cooling devices for the circulating systems of automobiles or the like, and to an arrangement thereof whereby the joints are minimized. the disposition of the radiating sl'irfaces to the air passages exposes maximum area of surface to the air while the construction as a whole is very firnrandcapable of resisting severe strains to which it\ is put inservice on a rapidly moving car.

The invention eonsists'in the matters hereinafter set forth, and more particularly pointed-out in the appended claims.

In the drawings, Figure 1 is a front end elevation of a radiator that embodies fea tures of the invention, the cellular construction thereof being shown diagrammatically; Fig. 2 is an enlarged view in vertical section through a portion of the cell structure of the radiator, parts being broken away; Fig. 3 is a view in transverse horizontal section through a' portion of the cells of the radiator; Fig. 4 is an enlarged view in detail of the end face of a portion of the cellular body of the radiator. showing the oil'- set margins of the component members; Fig. 5 is a view in detail of one of the rib plates, and Fig. 6 is a view in detail of one of the spacing plates.

Referring to the drawings. an upper header 1 and lower header 2 with side mem-- hers 3 are connected as a framework the body of which is filled with the cellular structure indicated generally at 4 that provides tortuous passages for circulating water or other cooling fluid from the upper header 1 to the lower header 2, inteISpersed with air cells or spaces extending from face to face ol the body.

The cellular body is formed of pairs of oppositely disposed rib plates 5 secured in spaced relation by the inset marginal porlions (1 thereof that are firmly united as by brazing, soldering or welding to insure a tight joint. The rib plates are transversely corrugated and at the alternate opposite crests of these corrugations are folded on themselves to form spacing fins 7.

Pairs of corrugated spaced ribless plates 8 are secured by their ofi'set margins 9 in spaced relation to form a tortuous or sinuous gupright flattened conduit for the circulation of water or other cooling medium, the

formed by the pairs of rib plates and pairs" of spaced plates, the structure is completed by a flange 10 formed on either of the plates, as the case may be, and infolded by the complemental members 11 of a lock seam flange formed on the contiguous member of either the spacing plate conduit or rib plate conduit. This insures a comparatively rigid construction at the end of the conduit thereby stillening the entire honeycomb body and providing convenient means for attaching the same to the upper and lower headers in the usual manner. I

In assembling the platesto form the rib plate conduit, the position of the fins at the crests insures their alternation on opposite sides of the conduits and likewise insures a proper centering of this conduit in respect to the other plate conduit adjacent to it. Because of the outfolding of the ribs from the conduits and the integral construction of the walls thereof there is no chance for leakage except at the union between the conduits and the headers and this is readily taken care of. l urthermore when assembled the honeycomb body may be readily made tight by dip soldering or the like as the joints are entirely at the outer faces thereof and around the edges and the whole can be quickly and easily manufactured. lt is extremely rigid because of thepeculiar bracing and centering ell'ect of the ribs and this makes it especially desirable for useon cars for heavy service \vhere'the vibrations might otherwise tend to disintegrate the body of the radiator.

Obviously, changes in the details of construction may be made without departing from the spirit of. my invention and I do not care to limit myself to any particular form or arrangement. of parts.

What I claim is:

1. A cooling honeycomb section for radiators the section being fonned of pairs of plates that are-tra nsverselcorrugated and are offset along the latera margins thereof and secured together, the plates 'ofonepair being folded on themselves at the crest of each corrugation to form spacin ribs and the'other platesbeing co'rrespo'n ingly corrugated' and bearing against the tips offthe spacing ribs in the depressions of the corrug: j'1ons of said platesfeach pair of connected plates includinga ribbed and rihless plate with the ribbed plates juxtaposed andthe ribless plates similarly positione'cl.'

2. A cooling honeycoinbed structure for radiators consisting of two adjacently positioned ribbed and transversely corrugated plates held .in spaced relation by the. inset marginal portions thereof with ribs projecting from alternate crests of the corrugations -oa opposite sides of the assembled pair pairs of. adjacently positioned ribless plates serorerlin spaced relation by the-inset mar giual portions-thereof, .the pairs of rib plates and spacing plates being disposed alternatel y 'withthe ribs oi the one restingmthe depressions of the other; the end portions of adjacent plates of the several pairs being folded togethertoT rm flanges atthe crests .of said corrugations on opposite sides -1of the duct, the rear faces of the ribbed plates being adjacently" positioned, and dis posed alternately with conduits formed of transversely corrugated spaced ril-iless plates adj'acentl'y positioned, the ribs of the com} the plates of each pair constituting a con .duit-heing held in spaced relation by inset marginal portions that are securedlin'abut ting relation the condmts'themsel'ves being -pamon conduits bearing in the depressionsof the conduits formed by the spaced plates,"

secured by companion flanges'folded around co ndu i ts.

In testimony whereof I. aflix my signature 7 in presenceof two witnesses.
